js json操作

var row1 = {};row1.name = 'david';row1.age = '20';//或者var row2 = {name: 'peter', age: '23'};var data = [];data.push(row1);data.push(row2);//此时data的json字符串为 [{name:'david',age:'20'},{name:'peter',age'23'}]//如果后台是PHP，将得到/*print_r($_GET);Array(0=>array('name' => 'david'....*/但是建议采用如下的形式var data = {records: []};data.records.push(row1);data.records.push(row2);//此时data的json字符串为 {records:[{name:'david',age:'20'},{name:'peter',age'23'}]}//如果后台是PHP，将得到/*print_r($_GET);Array(    'records' => array(        0 => array(            'name' => 'david'            ....*/

$('#setauth').click(function(){     var Ul = $('#autform').find(':text');     var all = [];     for(var i=0;i<Ul.length;i++)     {        all.push({key: UI[i].name, val: Ul[i].value});     }     $.post(url,all,function(data){... });})
